Problems solved by technology
With the end of cheap oil and the mounting peak of world oil production, it is recognized that petroleum is a non-renewable resource and will eventually be depleted.
Effectively, since ethanol-based fuels have lower energy, pollution is generally increased per mile.
It is a kinetic parameter, therefore difficult to predict.
This translates to aircraft range and to specific fuel consumption.
Aircraft cannot compromise range due to the sensitivity of their missions.
Although discrete chemical compounds have been found to satisfy the motor octane number for 100LL octane aviation gasoline, they fail to meet a number of other technical requirements for aviation gasoline.
These paraffinic fuels are not “drop-in” jet fuel for a number of reasons: first, their density falls below allowable 0.775-0.84 range; and second, they tend to cause fuel leaks through o-ring seals (due to the lack of aromatic components).
Thus, adding a single-component aromatic component to a fuel (as opposed to a wide-boiling aromatics blend like FIG. 1) might not provide satisfactory properties.
However, this reduction tracks well with the general trend of cetane reduction with aromatic content in jet fuels, so it does not exclude the use of mesitylene blends in diesel engines.
One expected issue with fully-synthetic fuels is lubricity.
Jet fuel lubricity is general thought to come primarily from trace polar impurities in jet fuel, so it might be expected that existing fully-syntheti...

Embodiment Construction
[0100]As discussed above, the present invention provides a non-petroleum-based renewable fuel comprised of fully renewable components, i.e., components derived from bio-sources such as corn. This fuel has several variants, the preferred variants being turbine fuel and diesel fuel. Advantageously, the components of the fuels discussed above are all derivable from plant or animal oils, and the product can be tailored to the input stock. In general, plant oils are preferred due to their lower molecular weight products.
[0101]Both the turbine fuels and the diesel fuels of the present invention provide an overall mix and match with discreet components derivable from all plant or animal oils, and the product can be tailored to the input stock. In general, plant oils are preferred as the base stock for production of the fuel component of the composition, due to their lower molecular weight products. With regards to same, the fuel component can be derived from various plant source bio-oils. ...

Abstract
A method of producing from a biomass mesitylene-isopentane fuel is provided. A biomass may be fermented to form acetone. The acetone is converted in a catalytic reactor to mesitylene and mesityl oxide. The mesitylene is separated in a phase separator and the organic face containing mesityl oxide is sent to a dehydration reactor, then to a demethylation reactor, and finally to a hydrogenation reactor from which isopentane is recovered. This isopentane is then mixed with the mesitylene to form the final mesitylene-isopentane fuel. The catalytic reaction with acetone employs catalysts of either niobium, vanadium or tantalum.
